DES MOINES, Iowa (AP) - The city of Des Moines and the Animal Rescue League are re-evaluating their longstanding partnership after concerns about the agency’s euthanasia rates and transparency.

The Des Moines Register (http://dmreg.co/1PNHNmg ) reports that the city delayed a $2.2 million contract with the agency last month after animal supporters questioned the agency’s kill rate and cooperation with residents.

City officials say they’re concerned and are considering using a different long-term animal control partner in the future. Officials from the agency say they’re re-evaluating their standing with the city.

But despite the city’s reservations, it’s expected to approve the agency’s three-year contract Monday night. City officials say there’s no one else that can step in and offer the services the agency provides.
